These data are supplement to: Takuya Hatomura, Univesal Digitized Counterdiabatic Driving, arXiv:2601.15972. In that preprint, Fig.1 consists of Fig1a.dat and Fig1b.dat; Fig.2 consists of Fig2a.dat, Fig2b.dat, Fig2c.dat, and Fig2d.dat; and Fig.3 consists of Fig3a.dat and Fig3b.dat. These data files are plotted without any processing. Fig_Supplemental_data_energy_gaps.dat lists the energy gaps between the ground state and the other energy eigenstates of a many-body system analyzed in that preprint (note that they are calculated in (N+1)-dimensional subspace). This data file is used in the all figures to draw supplemental lines.
